Abstract

L'invention concerne l'utilisation d'un élastomère thermoplastique dans un revêtement de sol pour un logement industriel pour bétail. L'invention concerne en outre un élastomère thermoplastique dans un revêtement de sol comprenant une ou plusieurs couches, de préférence au moins une couche étant un élastomère thermoplastique vulcanisé dynamiquement. L'élastomère thermoplastique comprend un polymère thermoplastique et un élastomère. L'élastomère est choisi parmi l’EPM, l’EPDM ou le SEBS et est de préférence vulcanisé dynamiquement. Le polymère thermoplastique est de préférence une polyoléfine, par exemple un polypropylène. L'utilisation d'un élastomère thermoplastique comprenant un polymère thermoplastique et un élastomère présente des propriétés renforcées de résistance à la fatigue et une meilleure résistance à la tension de corrosion, c’est-à-dire une meilleure résistance chimique et une meilleure résistance à la déformation. Un autre avantage est que l'élastomère thermoplastique comprenant le polymère thermoplastique et l'élastomère fournit une meilleure résistance à l'abrasion, ce qui peut être une propriété importante dans un logement pour animaux car elle empêche les animaux de glisser sur les revêtements de sol.
